Triangular craft with an odd luminescence coming from the bottom of the craft. It made no sound.This happened years ago but I didn't think much of it until I started noting that many of the reports are of these triangular aircraft. It all started after my two friends and myself were walking out of Dry Canyon right above Logan, Utah after hiking and having a simple cookout. The night sky was clear and we could see miles in all directions as you can in the desert on clear nights such as this. We were on the way home. No car was necessary as Logan is within walking distance of the Wasatch National Forest. I was talking to one of my friends when the other pointed over my shoulder and said, "What is that?" His voice had a timber that leant to the urgency of his exclaimation. I turned in the direction that he was pointing. SSW. I saw a triangular craft moving slowly in our direction. It fit the descriptions that I have been reading on this forum. It was triangular with 4 lights. Three small lights at the tips and one large light in the center that seemed to slightly illuminate the ground. It flew directly over us at about 1000 ft and we were illuminated slightly as the large central light passed over us. It made no sound. There were two smaller craft at each wing tip that could not be discerned except by there dark outlines. If you were to gauge their relative sizes, I would say they were approximatly the size of a minivan next to a bowing 747. The three craft went over us and continued NNE until we lost them in the night sky. The silence of the craft was earie. After some reflection on what we had seen, we thought it was simply a new form of military aircraft practicing bombing runs over Logan as Hill AFB is located near Ogden, Utah. I am also a skeptic considering I am a scientist and yet I have yet to see a craft such as this in any of the military arsenal since. This makes the encounter all the more interesting.((NUFORC Note: Date is approximate. PD))
